Current European guidelines recommend periodic risk assessment for patients with pulmonary arterial hypertension (PAH). The aim of our study was to determine the association between the number of ...low-risk criteria achieved within 1 year of diagnosis and long-term prognosis.Incident patients with idiopathic, heritable and drug-induced PAH between 2006 and 2016 were analysed. The number of low-risk criteria present at diagnosis and at first re-evaluation were assessed: World Health Organization (WHO)/New York Heart Association (NYHA) functional class I or II, 6-min walking distance (6MWD) >440 m, right atrial pressure <8 mmHg and cardiac index ≥2.5 L·min
·m
1017 patients were included (mean age 57 years, 59% female, 75% idiopathic PAH). After a median follow-up of 34 months, 238 (23%) patients had died. Each of the four low-risk criteria independently predicted transplant-free survival at first re-evaluation. The number of low-risk criteria present at diagnosis (p<0.001) and at first re-evaluation (p<0.001) discriminated the risk of death or lung transplantation. In addition, in a subgroup of 603 patients with brain natriuretic peptide (BNP) or N-terminal pro-brain natriuretic peptide (NT-proBNP) measurements, the number of three noninvasive criteria (WHO/NYHA functional class, 6MWD and BNP/NT-proBNP) present at first re-evaluation discriminated prognostic groups (p<0.001).A simplified risk assessment tool that quantifies the number of low-risk criteria present accurately predicted transplant-free survival in PAH.
Aims
To improve knowledge of epidemiological data, management, and clinical outcome of acute heart failure (AHF) in a real‐life setting in France.
Methods and results
We conducted an observational ...survey constituting a single‐day snapshot of all unplanned hospitalizations because of AHF in 170 hospitals throughout France (the OFICA survey). A total of 1658 patients (median age 79 years, 55% male) were included. Family doctors were the first medical contact in 43% of cases, and patients were admitted through emergency departments in 64% of cases. Clinical scenarios were mainly acutely decompensated HF (48%) and acute pulmonary oedema (38%) with similar clinical and biological characteristics as well as outcome. Characteristics were different and severity higher in both shock and right HF. Infection and arrhythmia were the most frequent precipitating factors (27% and 24% of cases); diabetes and chronic pulmonary disease were the most frequent co‐morbidities (31% and 21%). Over 80% of patients underwent both natriuretic peptide testing and echocardiography. LVEF was preserved (>50%) in 36% of patients and associated with specific characteristics and lower severity. Median hospital stay was 13 days; in‐hospital mortality was 8.2%, and independent predictors were age, blood pressure, and creatinine. Treatment at discharge in patients with reduced LVEF included ACE inhibitors/ARBs, beta‐blockers, and aldosterone inhibitors in 78, 67, and 27% cases. Non‐surgical devices were reported in <20% of potential candidates.
Conclusion
This comprehensive survey analysing AHF in real life emphasizes the heterogeneous nature and overall high severity of AHF. It could be a useful tool to identify unsolved medical issues and improve outcome.

Abstract Background Aging populations show higher incidences of myocardial infarction (MI) and heart failure (HF). Cardiac remodeling post-MI leads to progressive impaired cardiac function caused by ...a disarray of several processes including derailed autophagy. Microribonucleic acids (miRNAs) are known to be key players in cardiovascular disease but their involvement in cardiac autophagy and aging is not well understood. Objectives This study sought to identify new miRNA candidates that regulate cardiac autophagy and aging. Methods We exploited a high-throughput, fluorescence-activated cell sorting-based green fluorescent protein–LC3 detection method to measure the autophagic flux in cardiomyocytes after transfection of a precursor miRNA library consisting of 380 miRNAs. This was followed by a series of molecular and in vivo studies. Results Together with additional expression screenings, we identified miR-22 as an abundant and strong inhibitor of the cardiac autophagy process. Cardiac miR-22 expression levels increased during aging of mice as well as in aging neonatal cardiomyocytes in vitro by a P53-dependent mechanism. Inhibition of miR-22 in aging cardiomyocytes in vitro activated autophagy and inhibited cellular hypertrophy. Pharmacological inhibition of miR-22 post-MI in older mice activated cardiac autophagy, prevented post-infarction remodeling, and improved cardiac function compared with control subjects. Interestingly, similar effects were less pronounced in younger mice with significantly lower cardiac miR-22 expression levels. In addition, circulating levels of miR-22 in 154 patients with systolic HF were highly associated with early mortality. Conclusions We concluded that miR-22 is an important regulator of cardiac autophagy and a potential therapeutic target, especially in the older myocardium. Finally, circulating miR-22 provides prognostic information for HF patients, highlighting miR-22 as a promising therapeutic and biomarker candidate for cardiovascular disorders.
In this paper the Working Group on Myocardial and Pericardial Disease proposes a revised definition of dilated cardiomyopathy (DCM) in an attempt to bridge the gap between our recent understanding of ...the disease spectrum and its clinical presentation in relatives, which is key for early diagnosis and the institution of potential preventative measures. We also provide practical hints to identify subsets of the DCM syndrome where aetiology directed management has great clinical relevance.
Long-term outcomes in portopulmonary hypertension (PoPH) are poorly studied in the current era of pulmonary hypertension management. We analysed the effect of pulmonary arterial hypertension ...(PAH)-targeted therapies, survival and predictors of death in a large contemporary cohort of patients with PoPH.
Data from patients with PoPH consecutively enrolled in the French Pulmonary Hypertension Registry between 2007 and 2017 were collected. The effect of initial treatment strategies on functional class, exercise capacity and cardiopulmonary haemodynamics were analysed. Survival and its association with PAH- and hepatic-related characteristics were also examined.
Six hundred and thirty-seven patients (mean age 55 ± 10 years; 58% male) were included. Fifty-seven percent had mild cirrhosis, i.e. Child-Pugh stage A. The median model for end-stage liver disease (MELD) score was 11 (IQR 9–15). Most patients (n = 474; 74%) were initiated on monotherapy, either with a phosphodiesterase-5 inhibitor (n = 336) or with an endothelin-receptor antagonist (n = 128); 95 (15%) were initiated on double oral combination therapy and 5 (1%) on triple therapy. After a median treatment time of 4.5 months, there were significant improvements in functional class (p <0.001), 6-minute walk distance (6MWD) (p <0.0001) and pulmonary vascular resistance (p <0.0001). Overall survival rates were 84%, 69% and 51% at 1, 3 and 5 years, respectively. Baseline 6MWD, sex, age and MELD score or Child-Pugh stage were identified as independent prognostic factors. Survival from PoPH diagnosis was significantly better in the subgroup of patients who underwent liver transplantation (92%, 83% and 81% at 1, 3 and 5 years, respectively).
Survival of patients with PoPH is strongly associated with the severity of liver disease. Patients who underwent liver transplantation had the best long-term outcomes.
Portopulmonary hypertension is defined by the presence of pulmonary arterial hypertension in the context of chronic liver disease and is characterized by progressive shortness of breath and exercise limitation. The presence of severe pulmonary arterial hypertension in liver transplant candidates represents a contraindication for such a surgery; however, treatments targeting pulmonary arterial hypertension are efficacious, allowing for safe transplantation and conferring good survival outcomes in those who undergo liver transplantation.

•Portopulmonary hypertension is a severe complication of portal hypertension.•Therapies targeting pulmonary arterial hypertension improve cardiopulmonary haemodynamics.•Combining these therapies and liver transplantation is associated with excellent long-term outcomes.
Treatment for pulmonary arterial hypertension (PAH) has been underpinned by single-agent therapy to which concomitant drugs are added sequentially when pre-defined treatment goals are not met.This ...retrospective analysis of real-world clinical data in 97 patients with newly diagnosed PAH (86% in New York Heart Association functional class III-IV) explored initial dual oral combination treatment with bosentan plus sildenafil (n=61), bosentan plus tadalafil (n=17), ambrisentan plus tadalafil (n=11) or ambrisentan plus sildenafil (n=8).All regimens were associated with significant improvements in functional class, exercise capacity, dyspnoea and haemodynamic indices after 4 months of therapy. Over a median follow-up period of 30 months, 75 (82%) patients were still alive, 53 (71%) of whom received only dual oral combination therapy. Overall survival rates were 97%, 94% and 83% at 1, 2 and 3 years, respectively, and 96%, 94% and 84%, respectively, for the patients with idiopathic PAH, heritable PAH and anorexigen-induced PAH. Expected survival rates calculated from the French equation for the latter were 86%, 75% and 66% at 1, 2 and 3 years, respectively.Initial combination of oral PAH-targeted medications may offer clinical benefits, especially in PAH patients with severe haemodynamic impairment.
